The club captain indicated he might retire from Argentina but Mancini said: "It is important that a fantastic player like Carlos plays for Manchester City and the national team.
The national team is always important. "Would I mind if he carried on? No. But sometimes I would like Carlos and all players to stay here during the break. It is difficult when they re-start.
"The problem for me, like other managers, is that we have had players away on international duty. We work for two weeks with three players. It has been difficult."
